Fig. 19, "an elevation of the running board bracket; Fig. 20, a section of the same taken on the line 20-20of Fig. 19; Fig. 21, an enlarged detail view of a port-ion of a modified form of running board saddle having a wooden block to which the boards may be fastened by screws; Fig. 22, a transverse section of the same; Fig. 23, a section showing a modified form of carline for support- Fig. 24, a section of a purlin ilust-rating the 'means for fastening the same to the end plate of the car.

According to the construction shown in the drawings, the carlines 20 for supporting the roof are formed of metal, preferably pressed steel of U shaped section having a 'channel or trough for drainingS off water,

and are supported at their en uponthe side plates 21 of the car which are cut out to form seats there-for so that the water from the channel in the carline may discharge over the side of the car. The longitudinal members, that is the ridge pole 25, and purlins 24, are also preferably formed of lU shaped metal sections without flanges and are supported in depressed seats formed in the carlines for this purpose, as shown. If desired, openings may be formed in the points of support for the ing into the carlines.

The roofing sheets 23 are supported upon the carlines, ridge pole, and pur ins, the two side edges -of a sheet being arranged over the channels in the carlines and the top edge.l over the channel -in the ridge pole, the side edges being coveredy by the carline ca s 22 which rest freely upon the roofing s eets, while the upper edge is'covered in a similar manner by the ridge cap 33.

According lto my present improvement, all

purpose of drainof the weight of the running board at the ridge is carried directly by the carlines, and for this purpose, I provide a runnin board saddle 40 having one or more pro]ections 40" extending down within the carline and fitting between the side walls thereof, to. which it is rigidly secured by bolts 40. When ybolted in position, the flange 4.0a of the saddle is supported a fixed `distance above the roofing sheets and extends over the upper ends of the carline caps 22, and

l the depending s onably tight joint and permit a sliding f movement without clamping or pinching the roof sheets. This ives the desired flexibility to the roof to al ow for expansion and contraction of the metal and the bending or weaving motion of the car.

The running board saddle is preferably fprmed of a malleable iron casting having a to-p flange with seats for the boards 41 which may be bolted thereto, as shown in` Fig. 1, lugs being located upon theoutside edges and between the edges of the boards. If preferred, the top flange may be -dispensed with, and a wooden block/10e, may be bolted to the saddle to which the running boards may be fastened by screws, as shown lin Figs. 21 and`22. ing a linlng'beneath the-roofing sheets; and

For the purpose of locking the ridge pole against any longitudinal movement relative ,to the carlines, the saddle 40 may be provided with a depending flange 40d, fitting v into a notch cut in the ridge pole, as shown more particularly in Fig. 6. A similar lock for the purlin may also be made by having web of the carline cap engage a notch 1n the purlin, as shown in Fig.

lf7. Another means for locking the longitudinal members, either ridge pole or purlin, to the carlines, is shown in Figs. 17 and 18, where a small casting 24, which extends out bet-Ween vthe walls of the carline is riveted or otherwise attached or formed integral Vwith the longitudinal member. As a means lfor securing the ends of the purlins, flanges ,24", may be formed upon their ends which :may then be bolted to the end plate of the car, as shown in Fig. 24.

bottom of the ridge pole and purlins at the The carlin'e caps 22, preferably extend Efrom the saddle near the ridge to a point near the yeaves of the ca'r, and for the purpose of holding the parts in place at the point, and also for protecting the end of the channel in the earline, I provide carline ,hoods 60. The ends of the carlines may have flanges 20, which Hare over the side Iof the side plate, 21, and the hood 60 may be fastened directly to these flanges and to the side plate of the car, by bolts, 59,

yasindicated in Figs. 10 and 11. The hood extends over the lower yend of the carline cap 22, holding the same in place, and the roofing sheet is preferably bent down over lthe end plate and over the flange at the end sheets, the carlinc flanges and hoods directly against the side of the side plate and above the facia board 5,8, so that all of these parts may be within the outside line of the acia and be protected from being struck by objects along the track if they should happen to project far enough to reach the side facia board of the car. The end of the roofing sheet 23 and the flange 20a' of the carline may extend' part way out over the top of the facia board 58, as shown in Figs. 10 and 11, in order to insure the from the carline and roof out over the side of `said hoard, and prevent moisture from dripping in behind the board.

Similar hoods 66 are provided for the ends of the ridge pole 2e, which are lcut through t e end plates and have flanges 25, on the outside to which the ridge hoods may be bolted, as shown particularly in Figs. 8 and 9. These hoods also have flanges which cover the ends of the ridge caps 33, and the roofing sheets, and securely hold the same in place at the same time protecting the end of the channel in the ridge pole from which water may discharge out over board, as will be readily understood.

Another feature of my improvement relates to the running board extension from the ridge along the end to the side of the car, and comprises tw'o angle bars 62, having the vertical flange cut away at the end where the bars are bolted or otherwise fastened to the underside of the running boards 41 and resting at the other end upon a longitudinal bar 42, which is supported at one end on a bracket 63, fastened to the end plate of the car'and at the other end on a bracket portion of the carline hood of the end carline, as shown particularly in Figs. 2, 12, and 13, of the drawing. This carline hood for the end carline is provided with an vintegral projecting ortion, 60, which carries one end of the ar, 42, and extends down within -and'to the bottom of the carline in order to support the bracket a fixed distance above the roofing sheets. The boards, 43, of the running board extension-are then supported on the angle bars, 62, and between the vertical flanges thereof which protect the ends of the boards and the entire weigh-t thereof is carried .by the end plate and carlines so that no weight is brought to bear upon the roofing sheets. This forms a simple, strong, and durable construction and one entirely free from objections.

For supporting the running boards where thel same project beyond the end of the car, l provide an improved malleable iron bracket of the form'shown in Figs. 12, 13, 19 and 20, and comprising two side bars adapted to be bolted to the end of the car, and a cross bar having seats for the ends of' the boards with an integral flange subboards.

discharge of the waterthe end facie car, as shown in Figs. of the drawing. |The stantially iush with the to `of the boards for protectingtheir ends an sides, and lugs projecting' between the edges of said This forms a secure support to which the boards may be bolted, and protects thev ends of the boards from injury.

A preferred form of roofing sheet and carline capconstructionis shown in Fig. 16, in which the edges of the roofing sheets over the cai-lines are bent upward and over, form ing a hook-shaped section, as indicated at 23, beneath the carline cap 22, which may be formed of a shallow channel section vinverte-d and adapted to rest upon the roofing sheet both at the carline flange and at the outer end of the hook-shaped portion, 23. By means of thisconstrnction, an eX- cessive amount of water will be4 preventedrom draininginto the carlineeven under severe storm conditions, since the greater portion of the rain which may be` driven in under the carline cap will be deflected out again by the curved end of the root sheet and the channel in the carline Awill not receive a greaterv amount of water than can be readily drained oi through the discharge at its ends, thereby maintaining the interior of the car perfectly dry even in the scverest storms.

. Another v:feature `of my improvement relates to the means for securing the roof sheets, 23, at the corners of thecar, and consists in cutting the sheet diagonally inward at the corner for a short distance, then bending the same down over the corner m0 and binding the corner with a short band, 23a, which may be riveted at 23" to the main sheet or astened with lag screws 23e passing through both the binding strip and. main sheet into the sideorend plate of the 165 12, 13, 14 and 15 band, 23, may be bent out at its ends close to the heads of the lag screws, 23e., and thereby form a lock,

23, to prevent the screws from turning. n@ This serves to greatly stiften the roof sheets at the corners and prevents the fastenings from becoming loose.

In Fig. 23 is shown a 'modified form of carline having the top flanges extended 115 4downward and'outward at 20", to form lower flanges for supporting for intermediete lining sheets 29, of wood or other heat insulating material, which may be located beneath the metal roof sheets, 23, but not 120 necessarily in contact therewith. This serves to arrest or absorb much of the heat which may radiate' through the metal roof, and keeps the interior of the car at a much lower temperature.

From the foregoing, it will now be apparent that by means of the various features of my improvement, a metallic car root' may be constructed which will be simple, light, flexible and durable, one which 130 -saddles supported on the carlines a fixed distance above the roof sheets, and extending over the upper ends of the carline caps for holding down said'caps and the roofing sheets. l
